1. Nuclear Reactions (i) In class we went through the U-235 fission reaction. There is another nuclear fission reaction that can be used in a reactor and that is the plutonium-239 reaction. Write down what that reaction is for the fission of a plutonium if the daughter products are 134Xe, 143Zr and 3 neutrons. 23Pu= 239.0521u u= 1.6605x10-27 kg e= 1.609x10-19 JeV 134Xe = 133.9054u in= 1.0087u 29.Pu=240.0538u 193Zr = 102.9266u c=2.9979x109 ms! 235 U = 235.0439u (ii) What is...

oart A and B please ission Reactions In a nuclear fission reaction a heavy nucleus divides to form smaller nuclei and one or more neutrons. Many nuclei can undergo fission, but the fission reactions of uranium-235 and plutonium-239 are the principal ones that generate energy in nuclear power plants. This problem deals with balancing the fission reaction of the uranium-235 isotope as it undergoes bombardment from a neutron 14 of 36 > Review Constants 1 Periodic Table When a U...
